An improved coating composition having one or more polymeric binders dispersed in a liquid medium, wherein the improvement comprises an anti-sag and anti-settling effective amount of a copolymer comprising a polymeric backbone comprising recurring monomeric units derived from monomers selected from the group consisting of one or more alpha -olefins and one or more unsaturated carboxylic acids, said backbone having grafted thereto, by a covalent amide linkage, one or more polymeric grafts comprising at least one recurring monomeric unit selected from the group consisting of:-NHC(O)RC(O)NHR1 and -NH-R-C (O)-or a combination thereof, wherein R is an alkylene group of at least about 2 carbon atom, and R1 is R or aryl.
